To all fr0/tom t mog/concern:

Be it lrnown that l, Gunris B. From', a citizen of the United. States, residing at lllauwatosa, in the county of Milwaukee and State of lllisconsin, `have invented a certain new and useful lmprovenient hill-ydraulic Installations, of which the following isla specification'.

This invention relates to improvements" in certain cases is excessive. In order to reduce these costs of construction and transportation, it has been proposed to line turbine pits with steel plates, but this type of lining was not satisfactory for large diameter pits, as heavy and expensive reinforcements were found necessary to make the steel plate linings of sufficient strength.

With the present invention the pit is effectively lined at minimum cost with builtup structural metal, preferably in the form of bars of similar cross section. It is preferred to arrange the bars longitudinally one above the other and to employ flanged bars, the [langes serving as reinforcements and producing a lining which is suificiently strong to support pits of very large diameter. By employing structural bars of any of the standard cross sections, such as angle bars, channel bars or I-beams, the bars may be shaped and shipped to destination where they may be assembled to form the completed lining. The weight of the lining material as compared with that of a cast lining of equal strength, is considerably decreased, thereby reducing both the cost vand difliculties vof transportation.

A clear conception of an embodiment of the invention may be Ahad by referring to the drawing accompanying and forming a Specification of Letters Patent.

part of this specification in which like reference Acharacters designate the same or similar parts. i

The single ligure of thedrawing discloses a transverse vertical section through hydraulic turbine installation having the invention applied to theipit thereof.

The installation c lisclosediin the drawingy comprises essentially a vertical Francis turbine l mounted in a foundation a and having a vertical shaft 2 by means of which the turbine is direct'connected to the generator 8. it pit 9 is formed in the foundation 4 directly above the turbine l and permits access to the turbine casing 5, the main lstuffing box and the guide vane manipulating mechanism. The turbine l receives its actuating fluid from the penstoclr 7 through a series of movable guide vanes 6 Vmounted within thecasing 5, and exhausts into the usual tail race through a discharge flume 8. rlhe guide vaines 6 are provided with operating' stems l0 which are connected in the usual manner with the guide vane actuating mechanisms l1, l2; s

The portion of the turbine pit directly adjacent the turbine casing 5, is preferably made circular in form and is lined with a plurality of superposed channel section bars 13. The engaging flanges of adjacent bars 13 are preferably connected by means of rivets or other securing means. The bars 13 are preferably formed of mild steel and have their abutting ends connected by means of suitable-tie plates l5. As disclosed, the upper portionof the pit 9 is formed of somewhat smaller diameter than the lower portion thereof, thus forming a ledge extending over the lower portion of the pit. The ledge so formed is reinforced by means of a suitable ring ld formed of an angle bar or a flat plate.

lt will be noted that the use of channel section bars 13 to line the pit 9, provides a relatively` light, strong and simple lining for the pit. The bars 13 need not necessarily be in one piece, and would preferably be madein several segments in very large installations. These bars needV not be of channel section, as angle section bars or I-beams would in some cases be equally as efficient as the channel section bars. W'hile the pit of the disclosure has been illustrated as being circular, this pit may be of any other form Without departing from the scope of the present invention.

It should be understood that it is not desired to be limited to the exact details of construction shown and described, for obvi- Y ous modifications Will occur toria person skilled in the art.`

It is claimed and desired to secure Letters Patent,- Y

l. A pit lining comprising a plurality Y of longitudinally bent one-piece structural steel bars of standard cross-section having coacting longitudinal flanges extending away from the pit toproduce a smooth interior7 the opposite ends of each'bar being rigidly united.

2, A pit lining comprising a plurality of longitudinally curved one-piece structural steel bars of standard cross-section having united longitudinal flanges extending-away from the pit to produce a smooth interior, the opposite ends of each bar being rigidly united.

3. A pit lining comprising a pluralityl of one-piece structur'alsteel bars of standard cross-section .bent longitudinally and end Vunited to form rings and having coacting Vaxes of said rings.

In testimony whereof the signature of the inventor -is afliXed hereto.
